Khwarezm shah, Ala ud-Din Muhammad,Jital with metal fatigue!
« on: April 19, 2017, 12:09:28 PM »
This looks quite odd, I don't think I've seen a coin with such cracks as appear on this one, it's mint is ticketed as Kurraman but it doesn't look right ?

Has anyone an idea how this came about?

  it's weight is 2.85g

I think this is basically a delamination error. I think the mint at that time was not very good anymore in making a homogenous alloy and good planchet quality.
This one (Also Tye#294) has a similar problem, just bigger chunks have broken off:

Agreed. Metals were not evenly mixed. Amusingly, this happens even on modern coins. When will they ever learn, as Marlène Dietrich put it.

Ala ud-Din Muhammad may be the worst diplomat in world history. First, he made war on the Caliph in Baghdad, only to be defeated by the weather, then he ordered the death of a diplomatic mission from Genghis Khan. Pretty bad judgement, but you got a spectacular piece of history now. :)
